Somehow, my fortress ended up with a dog mayor. I do not believe that I modded the animals in such a way that this would be possible.
However, all my mods contain several modifications, consisting of the addition of sabers as a weapon (I noted that dwarfs had a word for this type of sword, but there was no such weapon), the addition of giant bamboo as a tree from which one can get timber, the addition of an alloy known as nickel aluminide, which consists of nickel and aluminum in 3:1 ratio, and is called "Brightsteel" (It is stronger, lighter, and faster than steel, but weaker than adamantine), as well as a modification to bubble bulbs, to change them from the o-shapes, which I found distracting, to the common . and , combination found in other grasses.
